with control lever.Safety shutdown and the prevention technology that relative position guarantees that contact or be in of the anti-technology Ka Tai that Fig. 9 introduction consists of with the second groove on the dead bolt and control lever opened the door.Figure 11 introduces and consists of anti-technology Ka Tai with the first end face (68) on the same control boss of dead bolt upper process and contact with control lever or be in the safety shutdown that relative position is guaranteed, and the prevention technology unlocking.And Figure 10, Figure 12 are shown in Figure 5 B-B figure that is in opening, Figure 10 is corresponding with Fig. 9, the preventing key that consists of with the first groove (45) on the dead bolt lose Ka Tai and control lever contact guarantee that door is under unlatching, A end on the described dead bolt can not contact with doorframe, prevents from unblanking key lock in doors.Figure 12 is corresponding with Figure 10, losing Ka Tai with the preventing key of the formation of the second table top (65) on the control boss (66) on the dead bolt contacts with control lever, guarantee door under opening, the A end on the described dead bolt can not contact with doorframe, and the key that prevents from unblanking is locked within doors closing door.Ask for an interview Fig. 5, Figure 10, the method introduction that the unlatching of Figure 12 door and door are closed: the lock owner is from going out within doors, the second handle (34) on the door is rotated (as shown in Figure 4), contact with the 3rd transmission boss or transmission groove on the dead bolt (9) through the transmission bar on the second handle, or the transmission bar on the 3rd transmission card contacts with the 3rd transmission boss of dead bolt upper process or the transmission groove of recessed dead bolt, dead bolt is moved, A on dead bolt end (4) withdrawed from from the hole (5) of doorframe (6) and in the access door (7), through push away or pull finish the door unlatching (such as Figure 10, door opening shown in Figure 12), when rotating the 3rd handle, dead bolt is moved, in the process that dead bolt moves, entered with the 3rd boss on the described drive link (40) by the transmission bar on the transmission bar on described the 3rd handle or described the 3rd transmission card and to contact, (not shown in FIG.), the 3rd boss is identical with the second boss (60) shape, make drive link (see Fig. 5 to described driving spring (14), Figure 10) direction moves, make transmission boss (53) on the drive link from Fig. 5, Fig. 9, dormancy point (52) on the described control lever (46) among Figure 11 moves with point (58) direction to described power through slide ramp (54), make described the 6th spring (36) compression on the drive link, press in the described transmission boss (53) on the control lever and slide ramp (54) on the control lever and to contact, make dynamic action point (58) mobile, and second spring (94) that will contact with control lever compression, the other end that makes control lever be drag effect point (43) to moving away from the dead bolt direction, the hook-type drag effect point (43) that is about on the control lever prevents that from dead bolt the second groove (44) of technology Ka Tai withdraws from, and disengage with the second groove (44), get so that dead bolt continues to be subjected to the rotation of the second handle and continue to move, at this moment, described transmission bar on the second handle or on the second transmission card and described the 3rd boss on the drive link disengage, make the 6th spring (36) that is in by compression discharge the elastic force elongation and with the drive link reset movement, make the moving application point (58) on transmission boss (53) and the control lever on the drive link, slide ramp (54) disengages, and when entering dormancy point (52) relative position, the second spring (94) elongation by compression discharges elastic force, the other end drag effect point (43) of control lever is contacted with the external surface of dead bolt, under being rotated further of the 3rd handle, after A end (4) on the dead bolt withdraws from the access door from doorframe (6), it is the position that contacts that the first groove (45) moves to described drag effect point (43) that preventing key on the dead bolt is lost Ka Tai, when door is opened rear the second handle reset movement, contacted with groove limit (91) on the first groove (45) by the point of the drag effect on the control lever (43), make dead bolt stop to move and (see Figure 10 for details, Figure 12), at this moment, it is interior or concordant with the door limit of door that A end (4) on the dead bolt is in recessed door, finishes the unlatching of door.A end on the described dead bolt can not stretch out outdoors, door can be closed with doorframe, therefore but can not contact with the collision of doorframe through door dead bolt is moved, door can not be closed, and the key of just guaranteeing to unblank is locked within doors closing Men Buhui, described a kind of the feature of this feature of Fig. 5 and Fig. 1, Fig. 3 is not identical, after Fig. 1 was a unlatching, A on dead bolt end stretched out in the door and at the door upper process, dead bolt can not be collided with doorframe contact, but dead bolt can not move, and door can not be closed.From going out within doors door is being opened rear (seeing Figure 10, Figure 12), need close without door, please see that at first preventing key is lost Ka Tai and anti-technology Ka Tai is the figure of the groove on the dead bolt, namely from Fig. 5, when door closure state shown in Figure 1 enters the opening of Figure 10 door, in the recessed door of an end A of dead bolt end (4).The first method of closing the door is dead bolt to be moved (again in conjunction with Fig. 5 with the capable release that is locked on the key opposite house of unblanking, Fig. 9, Figure 10 sees), under with door and doorframe closure, again by driving sword iron or the rotation of the first transmission card (18) by the key of unblanking in the key releasing process of unblanking, because the A on the dead bolt holds in the access door, the first transmission boss (42) is away from the first transmission card (18) on the dead bolt, therefore, transmission bar (20) on described the first transmission card (18) contacts with the first boss (41) on the drive link (40), making drive link is that the other end of drive link moves to the second boss (60), make the 5th spring (38) compression, transmission boss (53) synchronizing moving that drive link is continuous, transmission boss (53) is moved toward dynamic action point (58) direction on the control lever through slide ramp (54) from the dormancy point (52) (seeing Fig. 9) on the control lever (46), press when contacting in transmission boss (53) and slide ramp (54) on the control lever, make the dynamic action point (58) of control lever mobile, and the second spring (94) compressed, fulcrum on control lever (47), the other end drag effect point (43) of control lever is moved to the direction away from dead bolt, the groove limit (91) that drag effect point and the preventing key on the dead bolt are lost on the first groove (45) of Ka Tai disengages, under the elastic force of driving spring (14), make dead bolt mobile rapidly, A end (4) on the dead bolt enters again in the hole of doorframe, unblanking this moment, key only need drive sword iron or the first transmission card rotates less than 30 degree angles, unblank key just can from lock take off with, after the A end (4) of dead bolt enters doorframe, anti-technology card platform the second groove (44) moves to described drag effect point (43) position on the dead bolt, the drag effect point is entered in the second groove (44) be in groove limit (92) and contact or relative position, the closing smoothly and finish (being state shown in Figure 9) of door, the below introduces and the anti-technology Ka Tai among Fig. 5 and preventing key are lost the control boss that Ka Tai is used in the dead bolt upper process closes a method.See Fig. 5, Figure 11, Figure 13 and Fig. 6 and Fig. 7 for details.Because Figure 11, Figure 12 and Fig. 5, Fig. 9, only have anti-technology Ka Tai and preventing key on the dead bolt to lose card platform shape among Figure 10 different, and all the other structures etc. are identical, cause is in front to Fig. 5, Fig. 9, Figure 10, among Figure 11 with Figure 10, the structure of same parts among Figure 12, operating principle, connection or contact relation have been done detailed introduction, therefore at Figure 10, among Figure 12 difference is described, emphasis to control lever how with the anti-technology Ka Tai that adopts the control boss, the changes in contact relation that preventing key is lost between the card platform is described in detail: with aforementioned, the lock owner is within doors on mobile or rotary door, and second handle (34) of direction opens the door, the dead bolt that is in blocking (seeing Figure 11) is moved, when dead bolt moves, the second handle (34) contacts with the first boss (41) on the drive link (40) drive link is moved, transmission boss (53) on the drive link enter with control lever (46) on slide ramp (54) pressure contact, dynamic action on control lever point (58) is moved to dead bolt (9) direction, fulcrum on control lever (47) makes the other end drag effect point (43) of control lever move to the direction away from dead bolt, because door is under closing, described drag effect point (43) is in that the first table top (68) on the same control boss (66) with the dead bolt upper process is in relative position and at a distance of certain distance, this must so that dead bolt after mobile some distance, control lever is in fulcrum (47) is mobile, and drag effect point (43) is contacted with the first table top (68) on the described control boss (66).At this moment, the second handle is after turning an angle, disengage with described the first boss (41) on the drive link (40), be in the 5th spring (38) elongation of compressive state, make transmission boss (53) on the drive link mobile and disengage with slide ramp (54) or dynamic action point (58) on the control lever (46), enter on the relative position of the dormancy point (52) on the control lever, under the elastic force acting in conjunction of the 5th spring (38) and the 6th spring (36), described transmission boss (53) and dormancy point are in relative position, the second spring (94) that contacts with control lever enters elongation by compressive state and discharges elastic force, be drag effect point (43) along the contact of the boss surface on the described control boss (66) or sliding-contact with control lever one end, when the A end (4) of dead bolt withdraws from the access door from doorframe, when the second table top (65) on the described control boss (66) passes through described drag effect point (43), the second spring (94) make drag effect point (43) enter with dead bolt on Surface Contact, and contacted with described the second table top (65) by described hook-type drag effect point (43), at this moment, the second handle has reset movement under the spring of rotatory force (such as Figure 14 medi-spring) effect, described door is opened (see door shown in Figure 12 for details and be in opening), because the A of the described dead bolt of Fig. 5 end is in the recessed door under door is opened, can not dead bolt be moved by the way of contact that collides of described A end and doorframe, and door can not be closed.Just closing of door must be with the key of unblanking, and this has just solved closing Men Buhui will unblank key lock in doors.The situation of closing of door is as follows: in the capable release that is locked into of using outdoors on the key opposite house of unblanking, when the key of unblanking drives the sword iron rotation, transmission bar (20) on the first transmission card (18) among described sword iron or Fig. 5 contacts with described the first boss (41) on the drive link (40), make transmission boss (53) on the drive link enter with control lever on slide ramp (54) pressure contact, be that dynamic action point (58) moves to dead bolt (9) direction with the end on the control lever, fulcrum on control lever (47) makes the other end drag effect point (43) of control lever move to the direction away from dead bolt (9), the second end face (65) on drag effect point and the described control boss (66) is disengaged, driving spring (14) discharges elastic force by being compressed to elongation, A end (4) on the dead bolt is entered in the hole (5) of doorframe (6), finish the work of closing (namely entering state of closing door shown in Figure 11) of door.Enter in the process of doorframe at dead bolt A end, described hook-type drag effect point (43) is along the table top sliding pressure contact of control boss (66), when the first end face (68) on the control boss passes through described drag effect point (43), the second spring (94) elastic force by compression enters with the external surface of dead bolt (9) the drag effect point and contacts, and make the relative position that enters between the first end face (68) in drag effect point (43) and control boss (66) in a distance, that is to say, A end (4) on the dead bolt can move some distances outside doorframe, but can not disengage with doorframe, described the first end face (68) will contact with described drag effect point (43), dead bolt can not be moved again, door can not be opened, this has just solved the anti-technology of door under the closing problem of opening the door, make the door of unlatching enter safety shut-off state, finished with the key of unblanking and closed door, realized the automatic locking function of door, the key of having guaranteed to unblank can not be locked within doors.When the button (55) that automatically locks in the described door of Fig. 5 (7) setting, just can solve the old man that do not join the key of unblanking or child can be when not unblanking key after going out safe ready close door.Ask for an interview first Fig. 5, Fig. 9, door shown in Figure 11 under closing, automatically lock an end of button (55) from door (7) upper process, and the spacing termination of the other end of the button that automatically locks (56) contacts with the external surface of dead bolt (9) or is in in-plant relative position.The boss that automatically locks on the button contacts with the 3rd spring (93), door order, make the boss on the button that automatically locks contact to locate with hole on the door, the head (57) that presses on the button that automatically locks contacts with dynamic action point (58) on the described control lever (46) or is in in-plant relative position.Therefore close lower at door, external force makes the button that automatically locks can only move very little distance, described spacing head (57) on the button that automatically locks is contacted with the external surface of dead bolt, the drag effect point (43) on the control lever (46) can not be disengaged with described groove limit (91) or described the second end face (65).Door is in the state that closes that anti-technology opens the door, old man among the manager or child be not during the configuration overhead key, they also need to go out, do not configure the key of unblanking, can not the safety shutdown door after going out, in order to address this problem, make things convenient for old man and child to close door and remind the lock owner dispose the expense key door being provided with, confirming to unblank key with rear, handle and press the button that automatically locks and move, or insert to touch with the access opening the imitative button that automatically locks of key object in recessed door shown in Figure 12 of unblanking of matched key or other and bleed off pressure the button that automatically locks and move, just can be easily, easily door is closed, bring convenience for people's life, prevent from again unblanking key lock in doors.Therefore, at door Fig. 5 from closed condition, Fig. 9, Figure 10 that Figure 11 access door is opened, during Figure 12, in the dead bolt access door, make auxiliary flute (51) on the dead bolt (9) move to spacing termination (56) relative position of the button that automatically locks (55), therefore, when the key of need not unblanking is outdoors closed, at first under with door and doorframe closure, touch and press the button (55) that automatically locks mobile, described spacing termination (56) enters in the auxiliary flute (51) on the dead bolt, and make the button that automatically locks to move larger distance, make the dynamic action point (58) on the control lever (46) move larger distance through the described head (57) that presses, two kinds of situations are arranged: 1. this moment, a kind of is such as the fulcrum (47) of Figure 10 on control lever, with the mobile larger distance of the other end drag effect point (58) of control lever, consequently: a kind of is such as the fulcrum (47) of Figure 10 on control lever, the distance that the other end drag effect point (43) of control lever is mobile larger, groove limit (91) on drag effect point and the first groove is disengaged, under driving spring (14) effect, the A end (4) of dead bolt is entered in the doorframe (6) closes door, simultaneously, the second groove (44) enters with drag effect point (43) and contacts or relative position on the dead bolt.2., another kind is as shown in figure 12, through the fulcrum on the control lever (47) the second end face (65) on the control boss (66) of the other end drag effect point (43) of control lever and dead bolt (9) upper process is disengaged, under driving spring (14) effect, the A end (4) of dead bolt (9) enters in the doorframe (6) closes door, simultaneously, the first end face (68) in control boss (66) enter again with control lever on drag effect point (43) contact or relative position, make door under closing, the technology that can prevent is opened the door.Like this, automatically lock that just to have finished automatically locking of door be self-closing doors to button.Door shown in Figure 5, with the key release of unblanking, with door from close enter opening after, in the recessed door of A end on the dead bolt, then, handle on door is closed with door and doorframe in doors, handle only need be rotated less than 30 degree angles, described transmission bar or accessory drive bar on the handle contact with described drive link, drive link are moved and make preventing key tongue on control lever and the dead bolt lose platform to disengage, and driving spring moves dead bolt, described A end on the dead bolt is entered in the doorframe, finish the work of closing of door and since main purpose of the present invention be introduce close outdoors Men Shike guarantee to unblank key with safety door, the door of closing is in doors only sketched.
